Abstract
An ultrasonic device includes an ultrasonic transceiver that transmits an ultrasonic wave to a target at a predetermined interval, and that receives the ultrasonic wave reflected on the target so as to output a reception signal, a signal integration unit that outputs an integrated signal obtained by integrating the reception signals output within a predetermined period, and a position detection unit that detects a position of the target, based on a magnitude relationship between signal intensity of the integrated signal and a predetermined reference value.
